Eye protection when using Nuarc plate burner?

I finally found, and bought, a Nuarc plate burner for carbon printing. It's the newer model that uses a metal halide light source. The thing is EXTREMELY bright, and I'm wondering if it's safer to use some eye protection when exposing?? I put on sunglasses now, but wonder about the wavelength of the light emitted and whether the sunglasses are sufficient protection...Thanks...

My wife uses a 1000 Watt Nuarc unit for polymer photogravure. She made an opaque vinyl sheet that hangs around the thing when it's on and wears very dark glasses as well. Were it not for the opaque vinyl, I think a welder's mask or goggles would be sufficient for protection, but nothing less than that.

I'm sure you could grab some UV and ND10,000 filters, and some pipe-cleaners, and hack yourself a very nice-looking pair of goggles without needing to buy a welder's mask...

There used to be a sign up in the woodworking shop at my high school "noise loud enough to annoy, given time will destroy". The same is probably true of light, if it hurts to look at it, it ain't good for you...

An awful lot of electrons were terribly inconvenienced in the making of this post.

I've never heard of anyone before who DIDN'T know these kinds of lights are dangerous to look at! This is kinda common sense stuff, just like not putting you hand on a lit stove burner. Even my cats can figure that kind of thing out without reading an Owner's Manual.
